SCHOOL-DESK.

i Specification of Letters Patent.

Patented Get. 19, 1916.

T0 all w71 om t may; concern.'

Be it known that l, WILLIAM F. BERN- s'rnIN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful School-Desk, of which the following is a specification.

My invention relates to improvements in a desk, known as a school-desk, and consists in so mounting the seat theerof that when in its inoperative position it is entirely removed from the front of its support, whereby it will not be in the path of passers-by for contact of the clothes or hands therewith.

It consists also of a novel construction of the pivot or axis of the seat whereby a bolt, screw, or pin therefor is dispensed with.

It consists also of means for supporting said seat in a strong, durable and inexpensive manner.

It consists also of details of construction as will be hereinafter set forth and claimed.

The invention is satisfactorily illustrated in the accompanying drawing, butJ the important instrumentalities thereof may be varied, as long as they are included in the scope of the claims.

Figure 1 represents an exterior side elevation of a school desk embodying my invention. Fig. 2 represents a side elevation of a portion thereof on an enlarged scale taken from the inside of that shown in Fig. 1. Fig. 3 represents a vertical section on line zza-m Fig. 2. Fig. 4 represents an interior side elevation of a portion thereof. Fig. 5 represents a horizontal section on an enlarged scale on line g/-y Fig. 3.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates one of the sides of the desk which is composed of the curved standard 2, the inclined standard 3, the desk body 4 which is supported on said standards 3 and 2, the hori- Zontally-extending angular bar formed of the upper limb 5, the lower end of the standard 3 being sustained by the lip 6 which is turned out from said end, and the lower end of said standard is secured by the rivets 7 to the lower limb 8 with the lip 6 resting upon the upper limb 5. The lower limb 8 of said bar has the lower portion of the standard 2 connected with it, and said portion is continued downwardly below said plate, forming the rear leg 9 of the desk.

To the front part of the limb 8 is riveted or otherwise firmly secured the standard 10, whose lower portion constitutes the front leg 11 of the desk. The portion 12 of said standard l0 above the limb 5 has on its sides the inturned flanges 13 and 14, the ange 13 continuing downwardy joining the leg 11. rlhe flange 14 extends to the limb 5 and rests thereon, said flanges receiving between them the lower end of the verticallyextending plate 15 which is riveted to the upper portion of the standard 10. Gn the lower end of said plate 15 is an inturned foot 16 which rests on the adjacent portion of the limb 5, thus forming a strong support for said plate 15. On the exterior of said plate 15 and parallel therewith is a plate 17 which is riveted to the former and to the standard 10, thus firmly supporting said plate 17. y

The plates 17 and 15 are separated at their head portions 18 and 19 respectively forming between them a passage to receive the seat carrying tongue 20 which depends from the seat and is rotatable in said passage, it being noticed that the head 18 has on its side the concavo-convex annular bead 21,the tongue 2O has on its side the concavo-convex bead 22, and the head 19 has on its side the concave-convex annular bead 23.

The concave portion of the bead 21 of the head 18 receives freely the convex portion of the bead 22 of the tongue 20, and the concave portion of said tongue receives freely the convex portion of the head 19, consequently said tongue is mounted freely on said heads as its pivot, it being guided in its rotation by the respective beads, this being accomplished without the employment of a pivotal bolt, screw, or pin, and the piercing of the tongues and inclosing heads to receive the same as heretofore practised.

Rising from the tongue 2O is the neck 24 with which is connected by rivets or other suitable means the seat support 25. On the bottom of the tongue 20 is the lug 26, one edge of the latter forming the shoulder 27, and one edge of said tongue forming the shoulder 28.

Connectedwith the interior of the head 18 is the block or projection 29 forming a stop piece which is so disposed in relation to the shoulders 28 and 27, that when the seat is in position to be occupied, the shoulder 27 will abut said piece 29, as in Fig. 2, and when turned to be folded and placed out of the way, the shoulder 28 will abut said piece, as in dotted lines in Fig. 2, it being noticed that the seat may make a quarter turn and Vin whichever position it is placed, it will be limited in its motions by the piece 29 and so sustained thereat.

Attention is directed to the fact that when the seat is in the position shown in Fig. 1, its rear portionlas lowered enters the recess 30 which eXists between the standard 3 and the support of the seat, said standard being set back of said support so that when the seat is raised or placed in inoperative position it will enter said space, and so not be in the way of scholars passing in front of the desk, whereby the clothing` or hands thereof will not be caught on the seat.

The members thus far described are made of sheet metal struck-up, stamped, pressed or otherwise formed into the desired shape.

The heads 18 and 19 of the plates 15 and 17 respectively are connected by the bolts or screws 31 without interfering with the free rotation of the tongue 20 between said heads. The covering 32 of the seat shown in Fig. 1 has been removed from the support 25, Fig. 2.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a school desk, a leg, relatively fixed parallel plates on said leg, a seat, and a seatcarrying member disposed between said plates, said plates and member having interengaging annular tongues and beads and intermediate flat bearing surfaces constituting a boltless pivot for the seat with said tongues surrounding the said iat surfaces, the latter serving as the axial center, said member having a lug and shoulders, screws securing said heads in spaced relation with said tongues freely movable between them, and a stop block held in position by one of said screws.

2. In a school desk, a pivotal seat, a bearing member for the pivot of said seat, a standard on which said bearing member is supported, said standard being provided with inturned flanges, a plate provided with a foot and secured to said standard and to said bearing member, a plate parallel with the first-named plate and a horizontal limb on the frame of the desk on which said foot is supported, said plates being separated and constituting portions of the hinge on which the seat is adapted to be moved.

3. In a school desk, a desk body, a standard connected therewith, a horizontal plate extended forward of the standard, said standard having its lower end connected with said plate, and provided with an outturned lip which is adapted to be supported on said plate and a support for the rear end of said plate.
